'IMPRQVEMBNT 1N TURBINE WATER-WHEELS.

'.ihe Schedule referred tojn these Letters Patent and making part o! the game Be` tknown that I, ENOS EMERSON, of Smithport, in the county of McKean and State of Pennsylvania,

i have invented a certain new and useful Improvement `iii `a`speciesot` Turbine Tater-Wheels known as l Emersons Champion Water-`Wheel; and the' following is a full, clear, and exact description of the same,

reference being had to the accompanying drawing making a part'of this specification, in which* V\11igurel represents a plan or top viewotthe wheel,

with the cap or cover removed, showing the inlet 'and "outlet, and the space where the wa-ter acts on the wheel.

`Figure 2 shows arvertical front view ot the same in section.`

"lhe object of my invention is a elieap,fdui'able, and

` very `eiicient water-power for running any kind of machinery for milling or manufacturingpurposes, and

will run equally wellont of or submerged under `It consists in the .forni `and construction of the wheelthe 'posit-ion of the buckets, and the space for confining and compressing the water to the rim of `I'ive-sixtlisot` the circumference of the'wheel.

Toenableothers to make `and use my champion `water-wheels, I will describe the construction and operation more fully, referring to the drawing and the V letters marked thereon. i

The body of the wheelA may be made of wood or of cast metal, -the `armsb b yb made thin, and double-knife edged, so as to cnt"freely lthrough the water when the wheel andca-se D, in which it runs, is submerged.

`The leaves or buckets a a a, are madecurved, and set inclined back, to go in the direction with the current of the water as .it flows through the circular spiral passage, C, when it is conned in the case D, and compressed against the ,rim A, ve-sixths of its circumference, the entrance E to the passage C being `the rim. l I much greater than when it is discharged centrally, and the wheel runs more steadily,by being' compressed` nearly all the way round, and, when submerged, com 1 at least vetimes greater than the space c at the outlet F, which is one-sixth of the size of the circumference of the wheel.

flhe wheel A maybe made of any required size;, the greater the diameter the greaterwili be the leverage, as the water is confined further from the center,`

and acts entirely on the circumference, or outside' ot' 'lhe force of the same amount ot water is para-tively loses but little of its force, thereby possess-v ing great advantages over the ordinary turbine waterwheels in a cold, freezing climate, only requiring the vertical shaft B to be liberated from vthe ice to start.

the machinery. .y

My improved mode ot' constructing the champion water-wheel, and the case in which it runs, has been thoroughly tested for nearly two years, and demon-g strates the fact that more force is .obtained from a `given quantity of water under the same head than i'om any other wheel that has ever yet come to4 my knowledge.

Having' thusfully described my invention,

'What I claim, and desire to secure by Letters Pat- 'The wheel A, with its concave',back-inclined wings or buckets a a a, as constructed, when arranged to operate iu the case D, havingfa water-passage, C, which diminishes insize from the inlet E to the outlet F,

thereby compressing the flow of water onto a large` portion ot' the circumference of the wheel, as herein described.

In testimony Ywhereot` I have hereunto'set my hand in presence ot;
